yearning
A deep, strong longing for something you really want.
Yearning is a deep, intense longing for something that feels just out of reach. It's stronger than simply wanting something: when you yearn for something, you feel it as an ache in your chest, a pulling sensation that won't quite go away.
A person stranded on a desert island might yearn for home, feeling homesick in a way that goes beyond just missing familiar things. An athlete recovering from an injury might yearn to get back on the field, counting down the days with an almost physical need to play again. You might yearn for summer vacation during a long winter, or yearn to see a friend who moved to another state.
The word carries a bittersweet quality: there's both the pain of not having what you want and the beauty of caring deeply about something. When poets write about yearning, they often describe it as both wonderful and difficult, because the feeling reminds you how much something matters to you. A character in a story might yearn for adventure, freedom, or understanding.
Notice that yearning is patient and enduring. You don't yearn for your next meal or for recess to start. You yearn for things that take time, things that matter enough to carry in your heart while you wait or work toward them.
